,LASTING- SPECIFICATION forming part of Letters MACHINE.

Patent No. 236,218, dated January 4, 1881.

Application filed September 7, 1880. (No model.)

.- Monroe and State of New York, haveinvented a new and ImprovedLasting-Machine, ot'which the following is a specification.

The object of this invention is to provide a cheap, simple, and durablemachine whereby boots and shoes can be lasted in a better man- 4stretched.

Figure 1 is a side elevation of the device, partly in section. Fig. 2 isa sectional end elevation on line a: m, Fig. 1. Fig. Sis a crosssectionon line y 3 Fig. 2.

Similar letters of reference indicate corresponding parts.

In the accompanying drawings, A represents the frame, made of anysuitable material, and designed to be fastened on a bench Or table.

B is the last block or seat, constructed with a heel end, a, and a toeend, I), the top of the former being of sufficient height for work to bedone between it and the table, and being curved to fit the curve in thetop of the heel Of the last, and provided with a pin, 0, extending abovethe said curve, soas to enter the corresponding hole 0 in the last 0, asshown. The toe end b is made of corresponding height, with a curvedface, I), to receive the upperface of thetoeof thelast O, as shown. Saidseat B may be constructed of metal or wood, in one piece, as shown, orit may be constructedin two parts, united or in contact just back of thetoe, so that the heel part may be 'moved without disturbing the toepart, and

the length of the said seat B be thereby adjusted to lasts of difierentsizes.

Secured to the front-end timbers of the frame A, by bolt 61 or otherdevice, is a lug, D, tightened in place by a wedge, D, that extendsinward and has pivoted on it vertical pins ff,

so as to move in horizontal planes. The two levers E E consist ofmetallic bars inwardly curved to conform with the side outlines of thelast 0, near the bottom thereof, and are also curved flatwise to conformin a measure with the curve of the bottom of the said last 0, and saidlevers E E are provided with flanges g g, which extend inward about ahalf an inch, or thereabout, from their upper faces, so as to fit'uponthe outer face of the bottom of the boot Or shoe, (that is beinglasted,) along the sides thereof. These flanges g 9 may be integralparts of the levers E E, or may be made separately and be securedthereon by bolts, screws, or other suitable devices. The levers E E areof sufficient length for their rear ends to rest on an adjustable-restcross-bar, E, of the frame A, as shown, and are so hinged on the pins ff that they can be closed closely about the last 0 and the leather Fupon said last 0, and can be opened apart to permit the easy removal oflast 0 and the leather, F, that is stretched upon it.

.G is a flat metal plate, called a templet, of the general shape of thebottom of the. last 0, and provided with holes hh around its edge forthe engagement of the hooks H H, that suspend the clamps I I. Saidtemplet G is provided on its surface with lugs m m, by which it issuspended on pins n n from rods K K, which extend up through the top ofthe frame A and through a plate, G, fixed thereon, and have their upperends pivoted to eccentriclevers L L, that are themselves pivoted or ful-85 crurned on pins q, that pass through their curved slots sin the topsof the standards M M, which rise from the plate G, whereby said templetG and its connected clamps I I can be raised and lowered at will to anydesired extent.

N N represent holding or pressing screwbolts, that pass down throughsuitable screwholes, 0 o,in the plate G, and freely through the templetG, so that their points will rest upon thelastO. Theseholding-boltsNNare designed to hold the last 0 firmly down in itsseatduring the process of lasting a boot or shoe, and I they may be madeto screw up or down, as indicated in the drawings, or may be adjusted100 by levers or other suitable devices.

The clamps I I are suspended from the hooks H H with theirclamping-points downward to seize the edges of the leather F, and theyare provided with set-screws p p, for adjusting the gripe of theirjawsor points upon said leather F. Clamps of other construction may be usedfor this purpose; but those herein shown are effective.

0 is the gathering cord, designed to be drawn and tied around thestretched leather F, between the clamp I I and bottom of the last 0,after the said leather F has been sufficiently stretched, in order todraw it more closely in about the last 0, and to make it fit thereonmore smoothly.

To last a boot or shoe on this machine, I take the upper-leather, F, fora boot or shoe that has been prepared for lasting, and turn it bottom upand insert the last 0 therein bottom up, said last 0 having an insolealready tacked on the bottom. I then place the last O bottom up in theseat B, so that the pin 0 shall enter the corresponding hole 0 in saidlast 0, the toe of the last 0 resting in curve I) of the said seat B.Then I lower the templet G to the full extent, and adjust the clamps II, making them grasp the upper-leather F all around the edge thereof,first grasping at the center at the heel, then at the center at the toe,and then, at proper distances apart, all around the said leather orupper F. Then I force down the holding-bolts N N upon the last 0, thusforcing said last 0 firmly down on the seat B; and next I draw up thetemplet G by means of the eccentric-levers L L, thereby pulling up theclamps I I, and consequently the upper-leather F, closely to the last 0,at every point alike; and said last 0 being firmly held down, all thesurplus leather of the upper-leather F is then above the bottom of saidlast 0. I now close the flanged levers E E, thereby pressing theupper-leather F to the shape of the last G, all around the bottomthereof, at or about the insole, which has been tacked thereon. I nextput on my gathering-cord 0 about the said upper-leather F and draw ittight; then release the eccentric-levers, pull again on the cord 0, andsecure it, and the boot or shoe is then lasted all ready for tacking,which tacking may be done in the machine while the last 0 rests on theseat B on opening the levers E E; or the boot or shoe, or rather theupper-leather F, may be removed, with the last 0, to a place preparedfor the convenience of the tacking.

Having thus described my invention, I claim as new and desire to secureby Letters Pateut 1. A lasting-machine constructed substantially asherein shown and described, consisting of a suitable frame, A, last-seatB, curved levers E E, templet G, provided with hooks and clamps H I,respectively, eccentric-levers L L, connecting-rods K, holding-bolts NN, and gathering-cord O, as set forth.

2. The combination, with the clamps I, of

screws 1), hooks H, and the adjustable templet G, to regulate the actionof said clamps, as and for the purpose set forth.

3. In a lasting-machine, as a means for stretching and holding theleather F on the last 0, the combination, with the clamps I andholding-screws N, of the gathering-cord 0, substantially as herein shownand described.

4. In a lasting machine, as a means for stretching, forming, and holdingthe leather F on the last 0, the combination, with the clamps I andholding-screws N, of the curved levers E E, substantially as hereinshown and described.
